cakephp：提交空表单给出 HTTP 404 页面未找到错误

Question

如何防止我的用户提交空表单？ 当我这样做时，我在 IE 中收到 HTTP 404 未找到错误，在 Firefox 中收到空白页面。 没有显示任何验证错误。

我什至尝试将 else stmt 放入 StudentsController 的 add 函数中，但这也没有触发。 die(debug($this->Student->validationErrors)) 没有显示任何内容，

我在 StudentsController 中也有一个 beforeFilter 。但我不认为这会导致任何问题，因为我已经尝试通过评论 beforeFilter 来运行该网站。

Students_controller.php

 <?php
  class StudentsController extends AppController{
  var $name='Students';
  var $helpers = array('Html','Form','Ajax','Javascript');
  var $components=array('Security','RequestHandler');

 function beforeFilter()//executed before any controller action logic
{   
        //parent::beforeFilter();
    if(isset($this->Security) && $this->RequestHandler->isAjax() && $this->action = 'getcities'){
        $this->Security->enabled = false;
        } 

}


  function add(){

    if (!empty($this->data)){

            //$student=$this->Student->saveAll($this->data,array('validate'=>'first'));
            //var_dump($student);
                  if ($this->Student->saveAll($this->data)){
                     $this->Session->setFlash('Your child\'s admission has been received. 
                     We will send you an email shortly.');
                     $this->redirect(array('controller'=>'pages', 'action'=>'home'));
                  }else{
                     $this->Session->setFlash(__('Your admission could not be saved. Please, try again.', true));  
                  }

    } //for if (!empty....

    $states=$this->Student->MerryParent->State->find('list');
    $this->set('states',$states);

    $cities=array();    
}//end function
  }
  ?>

以下是我的经过验证的模型： 学生.php

  <?php
   class Student extends AppModel{
var $name='Student';
var $belongsTo=array('MerryParent','MerryClass','State','City');

var $validate=array(
        'name'=>array(
                'rule'=>array('minLength',3),
                'required'=>true,
                'allowEmpty'=>false,
                'message'=>'Name is required!'
                ),
        'dob'=>array(
                'rule'=>'date',
                'required'=>true,
                'allowEmpty'=>false,
                'message'=>'Enter a valid birth date!'
                ),
        'class_id'=>array(
                'rule'=>'notEmpty', 
                'message'=>'Which class are you enquiring about?'
                )
        //'city_id'=>array('rule'=>'notEmpty','message'=>'Please select your city','required'=>true, 'allowEmpty'=>false)
        );

} ？>

Answer 1

if (!empty($this->data)){
  if ($this->学生->saveAll($this->data)){
     $this->Session->setFlash('您孩子的录取通知书已收到。我们很快就会向您发送电子邮件。');
     $this->redirect(array('controller'=>'pages', 'action'=>'home'));
  }别的{
     $this->Session->setFlash(__('您的入场信息无法保存。请重试。', true));  
  }
}

编辑：当你收到 404 时，网址是什么？因为在默认的 cake 配置中，你只会遇到缺少控制器或缺少操作的情况，而不会出现 404 错误。你不需要发布模型，但需要发布你拥有的路线。
